Cooling holes shield components from temperatures that are often higher than their melting point, making their precise design and manufacture a critical feature of the engine. Components are often cast from high nickel and high cobalt alloys to enhance performance and longevity.

Winbro uses different processes to produce cooling holes – EDM, Laser Drilling, Laser Ablation or a combination of these. The choice of these technologies can be influenced by the particular coating applied to the part (Ceramic or Metallic), metallurgy / productivity requirements or component / feature access. Winbro Group Technologies has become recognised as a world leader in the development and implementation of these technologies for the production of cooling holes.

Now with the addition of the FGC 2 multi axis grinding machine manufactured by Winbro we offer the complete solution for finish grinding vanes.
